Answer: $350.00
Step-by-step explanation:
Answer:
$350
Step-by-step explanation:
if the sale is 30% we have to find what is 30% of 500 so we can subtracted from what we pay .
line up what you know:
$500 represents 100%
$x represents 30 %
cross multiply
x*100 = 500* 30 ; divide both sides by 100
x= 500*30 /100 = 150
the sale price is 500-150= $350
Mr. Kazadi said that in his 2nd-period class, 23 out of 25 students passed the test. What percent of the students passed the test?
%
[tex]\text{Hello there!}[/tex]
To find a percentage, you will need to divide both numbers by each other. In this case, it would look similar to this:
[tex]\text{23 / 25 = ???}[/tex]
Once you divide the two numbers, you should end up with a result of [tex]0.92[/tex]
Now, we are going to move the decimal two spaces to the right to end up with the result:
[tex]\text{092.}[/tex]
Now, we are going to remove the [tex]0[/tex] as it is no longer required. Next, add a percentage symbol to the last number, and remove the decimal from the number.
Now, you should end up with something like this:
[tex]92\%[/tex]
[tex]\fbox{So your final answer is going to be 92\%}[/tex]
[tex]\rule{299}{1.5}[/tex]

In Omak the sales tax is 8.4%. What is the total cost including tax Aakel spent on a $48 purchase?
Answer:
$52.03
Step-by-step explanation:
1. Approach
To solve this problem, first one needs to calculate the sales tax, then one must add that to the amount spent on the purchase. To calculate sales tax, one must convert the percent to decimal form, this can be done by dividing the percent by 100. Then one will multiply the decimal by the amount spent.
2. Find the tax
As states above; to calculate sales tax, one must convert the percent to decimal form, this can be done by dividing the percent by 100. Then one will multiply the decimal by the amount spent.
a. convert percent to decimal
8.4 / 100 = 0.084
b. multiply the decimal by the amount spent
48 * 0.084 = 4.032
The amount spent on sales tax is, $4.032
3. Find the total amount spent
Now all one has to do is add the amount spent in tax by the amount spent on the purchase.
48 + 4.032 = 52.032
Since money is only spent rounded to the second decimal point, one has to round the number;
52.03
Riley has a loyalty card good for a 12% discount at her local pharmacy. What would
her total in dollars and cents be, after the discount and before tax, if the total cost of
all the items she wants to buy is $17.50? Round to the nearest cent.
Answer:
The cost after discount would be $15.40
Step-by-step explanation:
Given that:
Discount card = 12%
Cost of items bought = $17.50
Amount of discount = 12% of 17.50
Amount of discount = [tex]\frac{12}{100}*17.50[/tex]
Amount of discount = 0.12 * 17.50
Amount of discount = $2.10
Cost after discount = 17.50 - 2.10
Cost after discount = $15.40
Hence,
The cost after discount would be $15.40

Answer:
6
Step-by-step explanation:
To evaluate the expression if a = 4, b = 3, and c = 2, substitute those values for the variables and solve. So, substitute 4 for a, 3 for b, and 2 for c, then simplify by the correct order of operations, PEMDAS:
[tex]ab - bc \\(4)(3)-(3)(2)\\= 12 - 6 \\= 6[/tex]

The Place valueof Thedigit 5 in 26,59,360 in Ten Thousand
Answer: True.
Step-by-step explanation:
Here we have the number:
26,59,360
To find the place value of the 5, we first need to count the number of decimals at the right of the 5 (until we reach the decimal point)
For this case, at the left of the 5 we have 4 decimals (9, 3, 6 and 0)
Then the place value of the 5 in that number will be 10^4
this is equal to:
10^4 = (10)*(10)*(10)*(10) = 10,000
This means that the place value of the 5 is then thousand.
Then the statement is true.

A certain radioactive material is known to decay at a rate proportional to the amount present. If initially there is 50 mg/L of the material present and after 2 hours it is observed that the material has lost 10 percent of its original concentration, find (a) an expression for the concentration of the material remaining at any time.
Answer:
[tex]Q(t) = 50e^{-0.0527t}[/tex]
Step-by-step explanation:
A certain radioactive material is known to decay at a rate proportional to the amount present.
This means that the situation can be described by the following differential equation:
[tex]\frac{dQ}{dt} = -rQ[/tex]
In which r is the decay rate.
Solving the differential equation by separation of variables, we have that:
[tex]\frac{dQ}{Q} = -r dt[/tex]
Integrating both sides:
[tex]\ln{Q} = -rt + K[/tex]
In which K is the integrative constant.
Applying the exponential to both sides, to remove the ln, we get:
[tex]Q(t) = Ke^{-rt}[/tex]
In which K is the initial amount present.
Initially there is 50 mg/L
This means that [tex]K = 50[/tex].
After 2 hours it is observed that the material has lost 10 percent of its original concentration
This means that [tex]Q(2) = 0.9K[/tex]. So
[tex]0.9K = Ke^{-2r}[/tex]
[tex]e^{-2r} = 0.9[/tex]
[tex]\ln{e^{-2r}} = \ln{0.9}[/tex]
[tex]-2r = \ln{0.9}[/tex]
[tex]r = -\frac{\ln{0.9}}{2}[/tex]
[tex]r = 0.0527[/tex]
So
[tex]Q(t) = Ke^{-rt}[/tex]
[tex]Q(t) = 50e^{-0.0527t}[/tex]
The observations X1, . . . , Xn have a mean of 52, a median of 52.1, and a standard deviation of 7. Eight percent of the observations are greater than 66; 7.9% of the observations are below 38. Based on this information, which of the following statements best describes the data?
a. The distribution has positive skew.
b. The distribution has negative skew.
c. The distribution has high kurtosis.
d. The distribution conforms to a normal distribution.
Answer:
d. The distribution conforms to a normal distribution.
Step-by-step explanation:
A normal distribution is when data has equal symmetry such that the distribution is not positive skewed nor negative skewed. A normal distribution has zero skewness as mean, median and mode are all equal.
In the above example, the data has a normal distribution because most values lie close to the mean(7.9 percent are less than 38 and 8 percent are more than 66)

Find two consecutive whole numbers that 54 lies between.
The two consecutive whole numbers that 54 lies between are 27 and 28, since 54 is greater than 27 and less than 28.
What is division?The division in mathematics is one kind of operation. In this process, we split the expressions or numbers into the same number of parts.
To find two consecutive whole numbers that 54 lies between, we can start by dividing 54 by 2 and rounding down to the nearest whole number since we want two consecutive numbers that are less than and greater than 54:
54 ÷ 2 = 27
So the two consecutive whole numbers that 54 lies between are 27 and 28, since 54 is greater than 27 and less than 28.

In the morning, Jasmine biked to her grandma's house in 45 minutes. When she was biking back home in the evening it was foggy and she went 4 mph slower. The trip back took her 1 hour and 10 minutes. How far from her house does her grandmother live?
Answer:
8.4 milesStep-by-step explanation:
Let the speed in the morning be s, then in the evening it is s - 4
The distance is equal both directions:
45 min *s = 1 hr 10 min *(s - 4)Time in hours:
45*1/60*s = (1 + 10*1/60)(s - 4)3/4s = 7/6s - 7/6*4Multiply all terms by 12 to clear fraction:

Answer:
[tex]180^{\circ}[/tex]
Step-by-step explanation:
Given that,
Total pies that sold = 700
Pumpkin pies = 350
We need to represent the degrees in the circle. It can be calculated as follows :
[tex]x=\dfrac{350}{700}\times 360\\\\x=180^{\circ}[/tex]
